Finishing of edges in the roofs of buildings

ABSTRACT

The invention relates to a device ( 16 ) for finishing the edges of armored concrete roofs ( 11 ) in buildings ( 10 ) and for holding facades ( 13 ). Said device has a projecting support frame ( 17 ) which can be fixed to the roof of the building in the area of the corresponding edge of the roof of the building ( 11 ).

[0001] The invention relates to a device for finishing the edges offloors, preferably reinforced concrete floors, of buildings and possiblyfor supporting facades.

[0002] Currently, for the purpose of finishing the edges of reinforcedconcrete floors, the reinforced concrete floor is extended or widened asa single piece in the form of a thin overhang. The facade is mounted onthis extension or widening section, which extends across the entirecorresponding area of the reinforced concrete floor. Facing elements orcovering elements are mounted on and a portion of the building-relatedmechanical and utility services are provided above and below thisextension or widening section. The provision of such an extension orwidening section in a single-piece design with the reinforced concretefloor results in a considerable formwork effort, which leads to anincreased cost and requires more construction time. The assembly of thefacing, covering and facade components is also complex. Moreover, only aportion of the building-related mechanical and utility installations canbe accommodated.

[0003] It is the object of the invention to create a device forfinishing the edges of floors, especially reinforced concrete floors, ofbuildings of the kind described above, which can be provided in a fastand inexpensive fashion and is essentially able to accommodate allconventional building-related installations.

[0004] To attain this object, the device for finishing the edges offloors, preferably of reinforced concrete floors, of buildings of thekind mentioned above is provided with the features disclosed in claim 1.

[0005] By utilizing an embodiment of the present invention, thecomplicated and complex formwork associated with forming a reinforcedconcrete like finishing edge is avoided, and a support frame, which iseasily mounted after producing the prestressed concrete or reinforcedconcrete floor, is created instead. The building-related mechanical andutility installations can be easily accommodated within the supportframe. Depending on the embodiment corresponding to the features ofclaims 2 and/or 3, the support frame may be composed of cantileversmounted side-by-side and one after the other on the reinforced concretefloor or affixed as a complete prefabricated unit on the reinforcedconcrete floor so that the complete support frame of a building edge isdelivered preassembled to the construction site. The embodimentcomprising individual cantilevers, either individually or in acombination, produces a weight reduction. The support frame ispreferably made of steel or aluminum.

[0006] Preferred embodiments include, in particular, adjustable mountingparts for attaching the support frame to the building floor or to afacade provided on the support frame having the features recited in oneor more of the claims 4 through 7.

[0007] Depending on how the building-related mechanical and utilityinstallations of claim 9 are accommodated, the support frame of claim 8is equipped with corresponding facing and/or covering elements. Thebuilding-related mechanical and utility installations may include, forexample, cable conduits, underfloor convectors, antiglare fixtures,sprinkler systems and the like, wherein the support frame may beprovided with a correspondingly perforated sheet metal covering or topair grille and otherwise perforated or non-perforated cover plates.

[0008] Pursuant to claim 10, the support frame or the individualcantilevers preferably exhibit an approximately channel-likeconfiguration in cross section, wherein this also includes crosssections in which the bottom side leg is not arranged in a horizontalconfiguration, but is inclined with respect to the horizontal plane ofthe building floor.

[0009] Further details of the invention are disclosed in the followingdescription, in which the invention is described and explained in moredetail based on the exemplary embodiment illustrated in the drawing.

[0010] The single FIGURE shows a partially broken off schematicrepresentation in vertical section through a building at the outer edgearea of a building floor.

[0011] In the building 10 depicted in the drawing, a prestressed orreinforced concrete floor 11 is represented seen from the edge, whichrests on a column 12 arranged below the floor 11 and supports a column12′ that extends upwardly from the floor to support other structures.Although only one column is illustrated, it will be appreciated thattypically a number of columns will be utilized and will be arrangedacross the floor and separated by various longitudinal and/or transversesections or distances. The building 10 is surrounded or covered by afacade 13 supported at a distance outward from the longitudinal edge 14of the building floor 11.

[0012] An edge finishing 16 of the building floor 11 is provided througha support frame 17, which both accommodates building-related mechanicaland/or utility installations, such as installations 31-34, and providesa mounting connection between the facade 13 and the building floor. Thesupport frame 17 may be made of stainless steel, aluminum or a similarmaterial and may be composed of several cantilevers 18, which arearranged periodically along the edge 14 of the building floor 11. Thesupport frame 17 or the cantilevers 18 are fixed or mounted on thebuilding floor 11, specifically on the face edge 14 as well as also onthe adjacent surface area 15 of the building floor 11.

[0013] The cantilever 18 has an approximately channel-like configurationseen from the side and comprises an inner leg 21 adjacent the buildingfloor 11, an outer leg 22, which is adjustably mounted on the facade 13,and a bottom side connecting leg 23. In the illustrated embodiment, theinner leg 21 is longer than the outer leg 22, while these legs arearranged approximately at the same upper edge height, so that theconnecting leg 23 is inclined with respect to the plane of the buildingfloor 11. Instead of this trapezoidal channel-like cross-section orlateral view of the support frame 17, the cantilever 18 can also bearranged to provide approximately U-shaped channel shape.

[0014] The cantilever 18 rests with the lower area of its inner leg 21attached to the face edge 14 of the building floor 11 via a firstadjustable mounting device 26. As illustrated, a mounting leg 24,arranged along a middle portion of the inner leg 21, may extendhorizontally over an upper surface 15 of the building floor 11 and beattached to the building floor via a second adjustable mount 27. Theinside leg 21 and the connecting leg 23 are firmly connected to thebuilding floor 11 in a fashion that is not shown in detail, wherein thealignment of the cantilever 18 can be adjusted or varied via the twomounts 26 and 27. The mounting leg 24 can also be held with a triangularconnecting metal sheet 28.

[0015] The support frame 17, which consists of several cantilevers 18arranged in a generally parallel and spaced arrangement, can beprefabricated in a workshop in accordance with the length of theaffected edge of the building floor 11 by connecting several cantilevers18 (not shown). In this way, the support frame 17 can be mounted as aprefabricated unit directly on the building floor 11. It is alsopossible to affix the cantilevers 18 individually to the building floor11 and subsequently connect the cantilevers 18 to form the support frame17.

[0016] The support frame 17 may be configured to accommodate most, ifnot all, conventional building-related mechanical and utilityinstallations or equipment, such as the cable conduit 31, underfloorblowers or convectors 32, antiglare lighting fixtures 33, sprinklersystems 34 and the like. The bottom of the support frame 17 or of thecantilevers 18 is formed by a facing metal sheet 36, which is mounted onthe bottom of the connecting legs 23 of the cantilevers 18. The facingmetal sheet 36 can also extend into a lower surface area 19 of thebuilding floor 11. The top of the support frame 17 or of the cantilevers18 may support, for example, air grills or vents 37 that provide outletsfor the underfloor convectors 32, and coverings 38 for shielding and/orconcealing the antiglare light fixtures 33 and sprinkler system 34. Asillustrated, the cantilever 18 includes additional reinforcement orsupport elements 29 and 30.

[0017] It is understood that the support frame 17, which provides forthe attachment of the facade 13 to the building floor 11 on the onehand, and accommodates the building-related mechanical and utilityinstallations 31 through 34 on the other hand, can also incorporate acorresponding fire protection lining, as well as heat protection andsound insulation materials.
